Can someone please help me to solve this question, 0.0000000009 ÷ 0.0003.Show your working. ​Pli​

0.0000000009 ÷ 0.0003 = 80000/

26666666667

= 3.0×10-6

Step-by-step explanation:

Conversion a decimal number to a fraction: 9.0E-10 = 9/

10000000000

= 8/

8888888889

a) Write down the decimal 9.0E-10 divided by 1: 9.0E-10 = 9.0E-10/

1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

9.0E-10/

1

= 9.0E-9/

10

= 9.0E-8/

100

= 9.0E-7/

1000

= 9.0E-6/

10000

= 9.0E-5/

100000

= 0.0009/

1000000

= 0.009/

10000000

= 0.09/

100000000

= 0.9/

1000000000

= 9/

10000000000

Note: 9/

10000000000

is called a decimal fraction.

c) Simplify and reduce the fraction

9/

10000000000

= 9 * 1/

10000000000 * 1

= 9 * 1/

10000000000 * 1

Conversion a decimal number to a fraction: 0.0003 = 3/

10000

= 3/

10000

a) Write down the decimal 0.0003 divided by 1: 0.0003 = 0.0003/

1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

0.0003/

1

= 0.003/

10

= 0.03/

100

= 0.3/

1000

= 3/

10000

Note: 3/

10000

is called a decimal fraction.

c) Simplify and reduce the fraction

3/

10000

= 1.5 * 2/

5000 * 2

= 1.5 * 2/

5000 * 2

= 1.5/

5000

Divide: 0 / 0.0003 = 8/

8888888889

· 10000/

3

= 8 · 10000/

8888888889 · 3

= 80000/

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 3/

10000

is 10000/

3

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - eight over eight billion eight hundred eighty-eight million eight hundred eighty-eight thousand eight hundred eighty-nine divided by three over ten thousand = eighty thousand over twenty-six billion six hundred sixty-six million six hundred sixty-six thousand six hundred sixty-seven.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
